SD — pumps pumps centrifugal horizontal, console one-stage with the driving wheel of the closed type.
The pumped-over environment: no more than 1x10-6 sq.m / with, with the temperature up to 363 To (90 °C), with the maintenance of the abrasive weighed particles no more than 1% on volume, up to 5 mm in size and microhardness, no more than 9000 MPas are intended for pumping of household, industrial sewage and other polluted liquids or clear water with a hydrogen indicator (rn) from 6 to 8,5, with a density up to 1100 kg/m3, with kinematic viscosity. The maximum size of not abrasive weighed particles depends on the section of the flowing channel through passage of the driving wheel.
Scope: for removal of household, industrial and waste (fecal) waters — at pump stations of transfer household, industrial and sewage.
Symbol: SD 800/32 (and, b), where
SD — waste and dynamic;
800 — giving, m3;
32 — a pressure, m;
and — turning of the driving wheel.
